Introduction

For the following reasons, plant protection sprayer cleaning becomes more and more important.

--- In order to avoid contamination of the environment and the operator;

--- Pesticide that may occur because of an accidental discharge causing crop injury, triggering fears of increased pesticide residues, or Caused by pesticides mixing several mutually exclusive.

In addition, the relevant industrial sector may need to provide development guidelines washing system to assess the level of technological development and future technology base.

GB/T 24684.1 and GB/T 24684.2 provisions of the relevant test methods and internal and external cleaning sprayer, to provide users Evaluation of internal and external cleaning system as well as the overall performance of a method to determine the future technical performance basis. This series of standards for the spray organs Key components provides a separate chapter (see GB/T 24684.3).

This section evaluation of cleaning a particular part of the system provides test methods in detail the results obtained may be improved and perfected cleaning systems Provide evidence.

GB/T 24684.3-2009/ISO 22368-3:2004 Plant protection machinery Test methods for the evaluation of cleaning systems Part 3. Internal tank cleaning WARNING. Users should be familiar with this part of the routine laboratory practice. This section related to the use of all possible security not addressed Wide issues. Users should make their own provisions appropriate safety and health practices and to ensure compliance with relevant national safety and environmental provisions.
